Your system is failing the POST, I think. You'll need to troubleshoot it by opening the case and unplugging everything but the CPU and memory and video. Now power it on. If there still is a problem, try removing one of the sticks of memory.
Once you isolate the problem, you can replace the part that has gone bad.

SOURCE: my tower wont turn off and monitor says no input signal and keyboard doesnt work

Do you have two video outputs on your PC ie. one on the motherboard adn a separately installed card maybe? If you do you need to set the BIOS so that it uses the AGP/PCIE video card and not the 'onboard'. Try the onbopard vodeo card first to see if you get a signal there.

If you do NOT have two video outputs, and you can not see a signal then you may have a prblem wiht your monitor itself. Is this a known working monitor to start with?

SOURCE: Got a used Compaq Pressario SR1303wm and need to set up correctly

Monitor into Small Blue connector at back.
If Mouse and keyboard are Round and not Rectangular in shape then that's a PS/2 Mouse and keyboard. Purple goes into Keyboard slot at back. Green goes into Mouse at back. Watch for the design as the pins inside each one need to be inserted accordingly.
If they ARE rectangular then that is a USB connection. On the back connect the keyborad and mouse to the top two. Again, only going to insert one ways.

SOURCE: mouse works, keyboard won't..plugged in another

try to plug the keyboard in another computer. If it is analog the lights dont come on the keyboard (caps lock, NUM lock, ect.) it is the tower if the lights do not turn on, it is the keyboard. If your keyboard is USB then try to use it on another computer if it doesnt work it is the keyboard, but if so I would make sure any software the keyboard came with is installed and try it agian.

SOURCE: I have a two year old hp that does not work. When

If you have access to a voltmeter I would check the power supply first. Take your cover off, and lay the computer down on its side, open side up. You should see a cable that provides power to your hard drive with an extra one that is free. The color of the wires are red, black, and yellow. Put the meter on DC volts and place the black lead in the black connector and put the red lead in the red connector. You should read +5 volts. Now move the red lead to the yellow connector, you should read +12 Volts. If either one of them is not correct, your power supply is bad. Replace it with a like type or one with a higher power rating to handle upgrades in the future. If the power supply is okay, then with the computer still on its side, look and see if there is a LED next to the CMOS battery. (A flat looking battery a little smaller than a quarter). If this is lit then you have power through the motherboard. Turn the computer back off and replace the CMOS battery. You may also try and reset the CMOS settings. There should be a jumper next to the CMOS battery. With the power still off, pull the jumper and place it across the other open post and leave it like that for about 15 seconds. Now put the jumper back in its original position, and put the new battery in. Turn the computer back on and see if anything is different. If same symptoms, then your best bet is to take it to a certified repairt person. Hope this helps.

Dell Dimension 3100 won't boot; keyboard fell off the table onto the tower; am getting 1-3-2 beep codes. Is this fixable?


Just because they hit the tower should not have hurt anything.

But, you should turn it off, pull the power plug, then hit the power button, then again and make sure the lights don't turn on or flash.

This make's sure that all the power is gone from the motherboard.

Before you touch the inside, make sure you touch metal, so you don't static shock the motherboard.

Now open the the side up. I would remove the two power connectors, one should be a 20-24 pin and another 4 pin.

Reset them to make sure they didn't come lose.

Check the HDD, hard drive plugs, fan plugs, the CPU fan plug.

Then check the monitor connection, and any on the back.

Try the monitor on another PC, or a monitor from another PC on this PC.

A hard shock to the power supply unit (PSU ) can kill it, it can still turn on the lights but not have the voltage to run it.

If you do all this and are safe and careful checking inside and out, then you might have to take it to someone who can test it.

You can also download the manual so you know what it looks like inside the PC and what the motherboard looks like and how you would set it up when new.

Good luck.

I have a zx4351, touch sreen wireless gateway desk top computer , i had cable co. today to hook it and now my screen does not turn on and has no power going to it what is it?


Your desktop tower/cpu tower has to be turned on to give those hardware power. If you can't turn on your computer then that means you have an internal problem with your motherboard etc. If everything else powers up except for the screen/monitor your video is dead. Find someone you know that has an extra monitor and hook it up to your tower, if it works then it's not your video but the monitor instead.

Monitor, keyboard and mouse not working HP Pavilon


Sounds like a component has gone bad on the computer. If you have a dedicated video card, I'd replace that first. Otherwise, it's likely the motherboard has gone bad and needs replaced. If this is the case, it's going to be just as expensive to replace the board as it would be to get a newer system.

I have HCL Ezeebee desktop computer when we boot the system monitor, keyboard, mouse blink for a while and monitor (HCL) show 'no signal' message, and keyboard num lock led not display mouse i


No signal at the monitor indicates (if you know the monitor is working ok) a failure of the graphics chip or graphics card, The lack of indicator light on the num lock LED and the lack of power to the mouse would indicate that there is a major issue with the motherboard.
you can try using another monitor to confirm the problem lies with the graphics, and in the case of the keyboard and mouse, swap them for a usb version, if they work, the Ps2 ports are probably damaged.
I'd be thinking of replacing the motherboard

Hi my wireless keyboard & mouse do not work at all on my Acer Aspire M3970, but both a cable keyboard & mouse do?


There is a USB receiver underneath the battery panel of the mouse, although it looks like part of the workings of the mouse. It's only a very small thing with a USB plug on it but it is there. The instructions don't show a picture of it, so it's very easy to think you haven't got one until you look closely

Unclip it and put it in your USB port and it should come up.

I was dusting my acer monitor and microsoft wireless keyboard and i must have hit something because now my monitor is reading sideways and the mouse wont work with it either. Can you tell me what I need to...


Sounds like you changed the orientation of your display settings from landscape to portrait.
In Windows 7 you can go to the control panel, choose display and click "Change Display Settings" on the left side.

From there choose the "Orientation" dropdown and change to your desired setting (most likely landscape)

Good luck

My emachine T1742 desktop will not turn on. When plugged in the power supply's fan turns on, cpu fan doesnt start, both hdd/power led's flicker and pressing power button doesnt power on/off system.


Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..
